To allj'wlwm it may concerns I ,Be it known that I, WILLIAM J'. KAU'FF- lVlAN, of Cleveland, Cuyahoga county, Ohio,

' the carriage roller and adjacent parts; Fig.

4 is a top' plan view; and'Figs. 5,6, 7 and 8 are sectional detail views hereinafter re-' ferred to.

My invention relates to typewriting'mer' chines, and is designed to provide paper guides which also act as adjustable marginal stops to give a uniform length of line ca pableof adjustment; also to so arrange the parts by which adjustment may be regulated the key lever shaft 12.

on the-ordinary scale in front of the ma-. chine which is used forthe purpose of indi cating the position of the'printing point.

In the drawings, 2 designates the car-' riage frame which is supported and moved in the usual way upon the 'slideways 3, 3. The vertical end supports 4, 4; of the carriage are: vertically slotted to receive ver tically movable guides 5, 5 thelower ends of which are secur (1 together by the connecting shaft 6. '%"he lower ends of the slides 5 rest upon the. tran verse shaft 7 extending across the machine elow the car riage and supported upon lever arms 8 v 8 which project upwardly and are forked at' their upper ends toengage circumferential recesses near the ends of the shaft 7.

9 designate end levers to which the'levers' 8 arepivotcd at their lower ends, and which are secured to rock shafts 10, which are operated in any suitable'manner, as by special keys which are arranged to raise and lower the roller; \Yith this-mechanism I employ a lifting lever 11 pivoted at its rear end to designates U-shaped devices Whichare rigidly secured to the end portions of the shaft 7 for the purpose of'insuring parallel lifting movement thereof. The oppositeendsof these arms are pivoted to the frame by means of the curved lugs 38 which fit arms or levers 37.

machine, as shown at Fig. 2, and may be held in place by pins;39 engaging cam faces '39 on. said arms. Whene'ver the shaft is,

moved vertically, each end is tur'ned to'ex actly'the same 1 extent by reason of these 40 designates. a. swinging type. guide mounted on collars 41 which round the shaft 7.

The parts thus far described constitute no partof my present invention, and are more fully described and shown in my pending application Serial 'No. 147,967, filed March 16th, 1903, of plication is a'diViSiflH.

' The paper guides consist'of c'urved arms 53 carrying rollers 54 at their upper ends, while their lower ends surround a transverse shaft 55 and are provided withpins or screws 56 entering a longitudinal groove partially surinthis shaft. The shaft is provided with whichthe present a'pa flat face along its front which is provided with notches 55' arranged to be engaged by latehes'57 secured to thelower ends ofleafsprings 58 screwed at their upperends to the paper guides. The shaft55 is a rock shaft which is mounted in end bearihgs'59 on the carriage, and is provided at itsrends with upwardly projecting arms 60 connectedby springs 61 with pins 62 projwting upwardly from lever arms' 63 secured to the shaft 64 of the feed roller '65, whichzis' covered withrubber and normallyldrg-wn against the carriage roller 65. One of the arms 60' is extended to form a finger lever 67, and the lower parts of both arms 60' are I formed with projecting levers 68 having ends with curved recesses which engage the 'leverarms'63l It is evident. that when the finger lever 67is drawn toward the operator,

the shaft 55 will be rockedto withdraw the paper guides from the carriage roller, while at the same time the feed-roller is forced away from the carriage roller against the '69 having an upwardly p'ro ecting wedge lip,70. The blocks may be a justed in the lots and clamped by'lowe'r nuts .71. Each of the wedges'is arranged so that when the carriage is.moved-to a position where. one

of t hepaper guides is immediately above it,*11 0 the wedge will act upon the lower end of the spring 58 so that when the finger-lever is actuated the tooth will be-withdrawn from the notch on the shaft 55. The operator then retains his finger upon the finger lever and slides the carriage along, the paper guide being held while the roller moves relativel to it. During this movement the scale 72 w lch is secured to the carriage moves along over the stationary pointer 73, thus indicating to the operator the position where he shall stop the end movement of the carriage to give the proper length of line. When this point is reached he releases the finger-lever and the spring on the paler guide throws the catch into engagementgrwith a notch on the shaft, thus retaining the paper guide in its new position. Either or both of the paper guides may thus be adjusted to any desired position and retained in such position. It will be noticed that the adjustment is obtained by holding the paper guide stationary and sliding the carriage relatively to -it,and that the paper guides also act as marginal stops. It will also be noted that when the finger lever is drawn toward the operator the paper is released and can be adjusted or drawn out as desired.

In order to disconnect the feeding mechanism to allow the end sliding of the carriage when desired Iprovide the bent lever 74 which is pivoted on a rear transverse shaft 75 and is secured to a lever-arm 76 connected by rod 77 with .a corresponding lever-arm pivoted to the shaft at the other side. The rod 77 when swung outwardly by pressing on the lever 74 acts upon a projecting portion 78 of the feeding lever and disconnects its dog 79 from the teeth of the ratchet wheel 80'. This enables the carriage to be moved endwise independently of the feed mechanism.

To provide for easy removal of the carriage and parts carried thereby from the carriage bed, and at the same time normally prevent such removal I provide a pivoted block 81 which is pivoted to the scale support at one end of the carriage. This block normally depends in the position shown in Fig. 1, but may be thrown into inoperative position. When in, such position the roller and parts carried thereby may be lifted to a point where the paper guides-will clear the stationary guides between which the type guide moves, and therefore the entire carriage may be slid off endwise after lifting it.

The carriage may be put back in place by sliding it endwise while lifted until the paper guide passes the stationary guides, when it may be lowered and the locking block thrown back into locking position.

83 designates a toothed wheel on the end of the roller shaft 82 forming part of the mechanism for hand-turning the carriage roller. 84 is a spring-pressed plunge arranged to gravity pawl arrange engage the teeth of the wheel 83 and hold the roller in adjusted osition. 85 is a loose to engage the teeth of the said wheel when the awl is forced forward. This pawl is provi ed with a collar seated in a recess in the sleeve 86, which forms-a hub of the hand wheel 87. 88 is a application above referred to, and constitute no part of my present invention.

The advantages of my invention consists in the arrangement of the paper'guides to act as the marginal stops, thereby simplifying the structure and reducing thenumber of parts; also in the arrangement of the parts so that the adjustment or length of the line may be regulated on the ordinarv scale in front of the machine.

What I claim is 1. A typewriter, having a combined paper guide and marginal stop secured to a rock shaft, and arranged to guide a sheet, means to rock said shaft, and means to release the stop for adjusting the same lengthwise of the platen when the shaft is rocked; substantially as described.

2. A typewriter, having two combined paper guides and marginal stops secured to a rock shaft and arranged to guide both sides of a sheet, means to rock said shaft, and means to release the stops for adjusting the same lengthwise of the platen when the shaft is rocked; substantially'as described.

In a typewriting machine, a carriage having a marginal stop secured to a rock shaft arranged to'move endwise with the carriage, and platen, means'to rock said shaft, and means to release the stop therefrom and for holding the stop stationary and permit the platen to be moved endwise in either direction relative to said stop; substantially as described.

In a typewriting machine, a carriage having a longitudinal rock bar or shaft, a marginal stop adjust-ably secured to the bar, moans to rock the bar and means to release the stop thcrcfrom and for holding the stop while adjusting the bar cndwia-av-in oithcr dircction relatively thcrcto; substantially as described.

(i. In a type-writing machine, a combined paper guide and marginal stop secured to a rock shaft, a second rock shaft, a feed roller mounted on said shaft, means to rock both shafts and means to release the marginal stop from the first shaft and to permit the means to release the marginal stop and paper guide from the rock shaft when said shaft is rocked; substantially as described.

8. A typewriting machine, a combined paper guide and marginal stop secured to a rock shaft, means to rock said shaft, and a cam adapted to release the marginal stop and paper guide from the rock shaft when said shaft is rocked; substantially as described.

9. A typewriting machine, having a combined paper guide and marginal stops adjustably mounted on a rock shaft mounted on the carriage of a platen, means for rocking the shaft, and means to release the combined paper guide and marginal stop from the shaft when it is rocked, to permit the carriage to be moved longitudinally relat-ively to the stops and paper. guides; substantially as described. 10. A typewriting machine, having a mov able carriage, a scale mounted on and movable with said carriage, marginal stops secured to. a rock shaft mounted on said carriage, means for rocking the shaft and means to disconnect the stops from said shaft to adjust said stop endwise in either direction relative to said carriage; substantially as described.

11. In a typewriter, a carriage having a rock shaft mounted thereon, a combined marginal stop and paper guide connected to said rock shaft, a stop on the carriage bed arranged to restrain endwise movement of the carriage when said marginal stops contact therewith, and a movable stop device normally preventing vertical movement of the carriage above a fixed level arranged to allow the carriage to be lifted to clear the endwise stop; substantially as described.

In testimony whereof, I have hereunto set my hand.
